ARTHUR ELPHINSTONE CUMMINS, OF 118 HAVERSTOOK HILL, COUNTY OF MIDDLESEX, ENGLAND.

BALE-PRESS.

SPECIFICATION forming part of Letters Patent No. 429,188, dated June 3, 1890.

Application filed July 31, 1889. Serial No. 319,299. (No model.) Patented in England March 12, 1888, No. 3,805.

To au whom it may concern:

Be it known that I, ARTHUR ELPHINSTONE CUMMINS, engineer, a subject of the Queen of Great Britain, residing at 118 Haverstock l-Iill, in the county of Middlesex, England, have invented certain new and useful Inprovements in Apparatus for Compressing Cotton or other Materials into Bales, (for which I have received Letters Patent in Great Britain, No. 3,805, dated March 12, 1888,) of which the following is a specification.

In the specification of a former patent granted to me in Great Britain, No. 15005, in the year 1885, I described a press in which two, three, or more filling-boxes were used for delivering material into abale-chamber to make up a bale, and the bale-chamber was provided with grids or movable fingers which retained the material in the hale-chamber when it had once been delivered into it. The bale-chamber was carried at the end of a swinging arm and brought first over one filling-box to have material discharged into it fromthis box, then brought over another box, and so on.

l According to my present invention I construct the press in such manner that the balechamber, after having the contents of two or more feeding-boxes delivered into it, can be brought over the top of the ram of a powerful hydraulic cylinder, so that the material may be finally compressed in this bale-chamber. I also construct the press without framing for taking any of the strains arising from the pressing of the material, so' that the cost of the press is much reduced and greater freedom in workin g it obtained. The several filling-boxes, with their hydraulic rams and the hydraulic cylind er for giving the final compression, I range in a circle, all independent one of the other. They may be buried in the ground or otherwise held in place by suitable supports. The horizontal arm which carries the hale-chamber I support upon balls or rollers which rest upon a circular bed, so that` the hale-chamber may readily be moved round in a circular path. WVhen the bale-chamber has been brought over the top of the hy-- draulic cylinder, I look it to this cylinder by lookin g nechanisn sufficiently strong to withstand the strain that will be brought upon it when the ram of the cylinder is giving the final compression to the bale of material in the chamber. Preferably I form the top of the cylinder with an outwardly-projecting flange and embrace it with a loose ring which has an inwardly-projecting fiange at the bottom. The upper part of' the ringI form with an internal parallel thread around it cut away in vertical segments. The exterior of the bottom of the hale-chamber I make circular and with corresponding threaded segmen ts on its exterior, To lock the bale-chamber to the cylinder, the ring is lifted upward until the projecting segments of the ring have passed into the spaces between the projecting segments on the chamber. A partial turn is then given to the ringto cause the threaded segments upon it to lock with the threaded segments on the chamber. The looking may also be performed without using threaded segments. Projecting segments engaging each other on a partial twist may be used. In this way the strains caused in compressing the material are carried by the sides of the cotton-boxes and bale chambers and cylinders, and hence the need of using framework to take these strains is done away with. The ring is supported by a lever carrying a counterbalanceweight, so that the ring (the weight of which would be considerable) can readily be raised and lowered.

The same means naybe employed "for locking the hale-chamber to the filling-boxes, or other ready means may be provided for locking it to these boxes, as the strains which will come upon them will be eomparatively light.

One, two, or more bale-chambers revolving independently or in conjunctionwith one another and one or two or more sets of fillingboxes may be used with one or more hydraulic cylinders for giving the final compression.

It is not essential that the filling-boxes and hydraulic cylinder should be ranged in a circle. They might, if preferred, be ranged in any other curve or in a straight line.

Figure 1 is a horizontal section, and Fig. 2 a side elevation, partly in section, of baling apparatus constructed as above described. Fig. 3 is an end view of one of the bale-chambers; Fig. 4:, a horizontal section on the line IOO 1 2; Fig. 5, a horizontal section on the line 4, and Fig. U a Vertical section of one of the bale-chambers with the side doors open. Fig. 7 is an end elevation,partly in section,of the nechanism for looking the bale-ehanber to the filling-boxes. The gearingis only shown applied to one filling-box, butsimilargearingis applied to each box. Fig. 8 is a Vertical section; Fig. 0, a cross-section of a modified construction of the press adapted for light bal ing. Figs. 10, 11, 12, and 13 show various Views, on a larger scale, of the locking-bolts by which the bale-chambers are held to the top of the iilling boxcs and the meehanism by which the bolts are actuated. Fig. 10 is a side elevation, and Fig. 11 a plan with the parts in the position they assume when the bolts are unloeked. Fig. 12 is a front elevation with part of the frame in section, showing one of the bolts in its locked position; and Fig. 13 is a section through tle line co b of Fig. 12. Fig. l l is au end elevation of one of the Vertieal ends of one of the bale-ehambers and the bolts carried by it. Fig. 15 is a herizontal section of the bale-ehamber, taken on the level of theline c (l of Fig. 14:, and Fig. 16 a horizontal section of the hale-chamber on the level of the line ef, Fig. li. Fig. 17 is aplan view of the locking-ring; Fig. 18, an end ele- Vation of the lower part of one of the balechambers with the lookin g-rin g in section below and disengagcd from it, and Fig. 19 a horizontal section through the lower part of one of the bale-chambers. Fig. 20 shows in section a modified construction of the central post around wlieh the bale-ehambers turn.

In Figs. 1 to 7, A l C are three filling-boxes, each fittcd with a novable bottom, which can be pressed npward by the ram of a hydraulic press X. D is the hydraulic press for finally eompressing the bales. E E are two balechambers, the bottom portions of which are carried by arms F' from rings F, which can swivel around the fixed eylindrical post G. Il ll are ball-bearings for the rings to run on. This post might, if preferred,be arranged underneath the floor-level, and the swiveling arns be made to revolve inside it, as is illustrated in the vertical section, Fig. 20.

\Vhen a hale-chamber is to be attaehed to one or other of the iilling-boxes, itis brought over the top of the box, and two T-headed catehes H which are jointed to the top of the box, are turned upward and inward and their T-heads made to come above projections l from the exterior of the bale-chamber, and so hold it down, as shown in detail at Fig. 12.

ln order to be able to turn the eatehes Il into position to lock the hale-chamber or to unlock it, each eatch ll has a beyel-pinion I-l' upon its axis, into which gears a corresponding pinion I' on inclined axes I. (See Figs. 2, 7, 10, 11, 12, and 13.)- These axes are geared by other beVel-pinions 15 and j with a horizontal axis J which can be turned whenever desired by turning an axis J' by a leverarm J which extends from it, the axis J having upon it a beveled toothed are j, gearing into one of the bevel-pinions on the axis J, or these eatehes may be worked in any other suitable inanner.

As shown in Figs. 2, 4, and 5, the botto'm part ol' each bale-chanber has a parallel thread around it cut away in segments.

To attach the hale-chamber to the top of the eylinder of the hydraulic press l), this cylinder has around it at the top an outwardly-projecting flange I), (see Fig. 2,) and is embraeed by a ring K, within which are segments of parallel thread, which project from the botton of the hale-chamber, or plain segments without thread might be used. (See Fig. 18.) \Vhen the hale-chamber has been brought over the cylinder of the press, the ring is raised until an inwardly-projeeting flange around its lower end comes against the ilange wlich is around the top of the eylinder. A partial turn is then given to the ring to cause its segments to engage with the segments on the bale-ehanber. The ring is turned by handles K', which stand out from it, or in other suitable way, the power necessary being very small. In order to be able to readily raise the ring whenever it is required to do so, the ring is supported on one end of leVer-arms L, (see Figs. l and 2,) which at their opposite ends have weights L' hung onto them nearly to balance the weight of the ring. The ring being tlus approxinately balanced, it can readily be raised by a man putting his foot on a treadle ili and putting increased weight on the weight end of the lever-arms.

Each hale-chamber is at the bottom formed with a series of parallel slots through two of its opposite sides for the grid-fingers N, (see Fig. 6,) which are to retain material in the hale-chamber. The grid-fingers are segments of disks,and eael set of grid-fingers is carried by an axis O, as in bale-ehambers heretotore made by me.

- The bale-ehambers thenselves may be constructcd in any suitable manner. In the construction shown in the drawings the lower portion of the bale-chamberis fixed to one of the arms F'. Two opposite sides of the chainber are at the bottom jointed by horizontal hinge-;joints c to the lower portion. At the top they are drawn together by turning a serew-spindle O which has right and left handed screw-threads upon it working in gun-metal nuts fitted in pockets east in the sides, and the sides hold between them the top P of the chamber. The other two sides are jointed by Vertieal hinge-joints Q to one of the sides, and can be turned around Vertical axes Q, and can be locked in their closed position by bolts R, as best seen in Figs. 4 and 14. \Vhen the doors are closed, the bolts R are slid endwise to lock them by eccent'ics on the pins Q of the hinge-joints. In order to be able to turn the pins Q, each pin has upon it a worrn-wheel S, into which IOO TIO

gears a worm T on aspindle U, which can be turned by a hand-Wheel V upon it. As before stated, the bale-chambers might be made to run upon a straight or Curved track to bring them first over the filling-boxes and then over the finishing hydraulic cylinder; but I prefer to mount them upon arms which swivel around or inside of a Central post, as above described.

In the modified construction of press shown at Figs. 8 and 9, A B are two filling-boxes, each fitted With a movable bottom, which can be pressed upward by the ram of a hydraulic cylinder, as in the press above described. C is a third filling-box fitted with a movable bottom,which can be pressed upward by a ram X of larger diameter than the rams used with the boxes A and B. E is a hale-chamber which can swivel around the central post G. On the outer side the box is supported on small Wheels oc, which run on the top of thefixed bed-plate Y. H are T-headed-catches jointed to the frame which carries the filling-boxes. By these catches the hale-chamber can be locked above either of the filling-boxes. The catches H hold down the hale-chamber just in the same way as the catches H shown in' Figs. 10, 11, 12, and 13; but in place of their being turned by gearing, as shown in those figures, they can be turned by hand either into a vertical position to look the hale-chamber and hold it down or be turned downward to release it. The bale-chamber is also prevented from rising by the head of the post G. The bale-chamber itself may be oonstructed in the manner hereinbefore described, or in other sutable' m anner.

\Vhat I claim is-- 1. The combination of ahydraulic cylinder, a filling-box fixed at the bottom to the top of the hydraulic cylinder, the movable bottom of the filling'-box constructed to be pressed upward by the ram of the hydraulic cylinder, a hale-chamber adapted to be brought over the filling'-box, grid-fingers for preventing the return of material fed into the bale-chamber, and catches to look the bottom of the balechamber to the top of the filling-box.

2. The combination of two or more fillingboxes, each fixed at the bottom to the top of a hydraulic cylinder and arranged in a circle, a pivot-post at the center of the circle, a hale-chamber carried by an arm which can turn around the post, grid-fingers which prevent the return of material fed into the balechamber, and catches to look the bottom of the hale-chamber directly to the top of either of the filling-boXes.

3. The combination of two or more fillingboXes, each fixed atthe bottom to the top of a hydraulic cylinder arranged in the are of a circle, a hydraulic cylinder in the same circle on the opposite side of the center, a pivotpost at the center, a bale-chamber carried by an arm which can turn around the pivot-post, grid-fingers which prevent the return of material fed into the hale-chamber, and devices for locking the bottom of the hale-chamber directly to the top of either of the fillingboxes or to the hydraulic cylinder.

t. The combination of two or more fillingboXes, each fixed at thebottom to the top of a hydraulic cylinder arranged in the are of a circle, a hydraulic cylinder in the same circle on the opposite side of the center, a pivotpost at the center, two or more bale-chambers, each carried by an arm that can be turned around the post and independently one of the other, grid-fingers which prevent the return of material fed into the hale-chambers, and catches to look the bottom of the bale-chambers directly to the top of either of the filling-boxes.
